Re: Bosch 5300 Dishwasher
This sounds like a thermal stop as well. The unit wants to get up to a final rinse tempurature but can't reach it so just keeps going. If you have an amp probe you can check to see if the heater is coming on in the final rinse. If it is not, could be the thermistor of even the heater.
a 6ya Repairman can help you resolve that issue over the phone in a minute or two.

The dw was not quite running. It does pause between cycles. The power scrub cycle means that you had the machine on the longest of all cycle choices. There's almost always a light and a normal cycle. The pots and pans cycle is a power scrub option. Yes all the lights would be on until they switched to a different part of the cycle. Do you have a DRYING light? That would be the one to look for as far as the dw being finished. :)
My Bosch DW SHU5302 also got stuck during a cycle and ran and ran. Turns out this is a known problem with these DW's. The problem is that a trace on the main board burns off that controls the heater. If the heater doesn't come on then the DW keeps running waiting for the water to heat up. Re-soldering this trace fixes this problem. If you get a repair guy out, he will only change the board. They are not allowed to re-solder which doesn't fix the problem for long as the same trace will burn off. Did this about 8 years ago and it is still fine.
From your description, I doubt that the problem is door latch is the cause.
The first thing that a modern dishwasher does before it begins to fill with water is run the drain pump. It appears that this DW is not progressing to the next cycle (inlet water) and because the pump runs even when the door is open, I agree that the controller card may have failed.
If possible, inspect all the wire connections (remove main power before you do this) ... if there is a loose connection, the controller could do odd things.
Good Luck! Please report back what you find, OK?
Begin at your sink drain that the dishwasher drain hose connects to. Disconnect the hose and check both directions for anything plugging the connection.
Make sure the drain hose has not become "kinked"
(After you have emptied the water from the dishwasher) remove the lower spray arm and the filter in the sump area. Look for obstructions and remove all debris. Rinse the filter thoroughly and reassemble.
If you dishwasher has a timer on the front of the dishwasher that you can manually turn, start a quick cycle with no DW soap and empty.
Allow the water to run in for several seconds and then manually (slowly, gently) turn the timer knob until the DW should begin draining the DW. Listen closely for the sound of the pump motor running.Is water properly draining out of the dishwasher into the drain?
After you have done these things, please post back here and we can take the next steps. OK?
On a Bosch dw, it has a light sensor to sense soil in the water.. if the control feels that the water going through the sensor is not clean/ or clean it will add or minus time..one thing you can do is make sure that your drain line from dw to sink drain is cleared of debris.. also, make sure you clean the filter at bottom of dw and make sure its reinstall correctly if you haven't already do so.. if your dw finish the cycle and come out clean, then the time on your dw is fine,, but if it don't finish and come out dirty.. then, it could be something other, but don't know til I get the full details on problem.. help this will do it for ya.. good luck.. mike
Mine did that. I tried changing the timer but it didn't help. I noticed that the water level kept rising until the drain pump would be triggered by the overfill protection switch on the left side under the insulation. It turned out that the fill valve didn't close all the way and so the pan would never empty. A new fill valve (easy to install and cheap) fixed it!
Bosch dishwashers have a seperate pump for washing and another for draining. Try making it fill more than once. There is usually a timed fill and the float stops it before it overfills It also might prevent it from washing without enouth water Try defeating the door switch and play with the float during fill. There may be a sensor that won't let it go into wash. Be prepared to get a little wet if it should start up suddenly. A slightly safer way is to fill it with the sprayer from the sink. and see if it will go into wash.
there is a new product out that actually filters the water going into your dishwasher. I use to have ugly,white and cloudy looking glasses until i installed this product. after the first load my glasses looked fantastic!!!! its affordable and you can get it at dishwasherfilter.com.
